1990: London split into 071 and 081 numbers. This should have doubled
the number of lines available but the idiots forgot to allow the re-use
of the first 3 following digits (the exchange code). Thus if 071 932
xxxx existed, you couldn't have 081 932 xxxx.
1995: 071 and 081 changed to 0171 and 0181 for no apparent reason.
(Actually I think they realised their previous mistake).
2000: 020 area code introduced and all local codes lengthened by
prefixing with 7 (for 0171) and 8 (for 0181). The 3 prefix was
introduced about 5 years later.
